A standard rectangular waveguide typically measures 22 mm wide and 10 mm high, supports TE10 mode with a cutoff frequency around 6.56 GHz, and is used primarily in high-frequency applications like radar. Shape and size The core design parameters of a rectangular waveguide include width and height, which directly determine the cutoff frequency of the […]

A rectangular waveguide acts as a high pass filter due to its cutoff frequency, determined by its width. For a width of 2 cm, the cutoff frequency is approximately 7.5 GHz, allowing only signals above this frequency to propagate effectively. Cut-off frequency The width of a waveguide is 2 cm, according to the cutoff frequency

The most common cause of failure in coaxial cables is physical damage, such as bending beyond the recommended radius, leading to a 40% increase in conductor breakage and significant signal loss. Physical damage Physical damage to coaxial cables often occurs in the inner conductors and outer insulation of the cable, especially during incorrect use and

Low SWR on a coaxial cable minimizes power loss and equipment stress, ensuring more of the transmitted 100 watts reaches the antenna, enhancing signal strength and reliability. Power efficiency Suppose a radio transmitter with an output power of 100 watts is connected to the antenna via a coaxial cable. We compare system performance with SWR

Satellites can transmit over vast distances: LEO satellites cover about 1,500 km in diameter, MEO satellites up to 5,000 km, and GEO satellites can reach about 42% of the Earth’s surface. Low Earth Orbit (LEO) satellites Low Earth Orbit (LEO) satellites orbit between 160 and 2,000 kilometers above the Earth. They’re so close to the

Optical fibers primarily use LEDs for short ranges (850 nm) and laser diodes for long distances, operating at 1310 nm or 1550 nm to minimize loss and maximize efficiency. Leds are used for short distances Leds are like right-hand men in short-range fiber optic communications, handling lightweight tasks in the world of data. Let’s dig
